FLUSEING- VALVE.

Application filed May 25, 1925. Serial No. 32,635.

To all whom it may concern:

Be it known that l, FREDERICK A. SoHossow, citizen of .the UnitedStates, residing at Detroit, county of Wayne, State of Michigan, haveinvented a certain new and useful Improvement in Flushing Valves, anddeclare the following to be a full, clear,'and exact description of thesame, suchas will enable othersskilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

My invention relates to a valve for flushing closet bowls or for otherlike purposes and is designed more particularly for use in combinationwith a pressure tank so designed that the water deliveredto the tankfroma water supply system under pressure compresses the air within thetank-the com- ;pressed air afterwards subsequently serving as a mediumfor expelling thefwater from the tank with sufficient force to maintaina siphon in the closet bowl for a predetermined period of time.

Flushing valves have been used in connection with pressure tanksin themanner indicated but so far as known these valves are designed so thatthey begin to close immediately. [following their manual operation, thevalve closing entirely under full pressure .in a limited length oftime,-thereby necessitating the employment of a tank adapted to receivemuch more water than is actually used at each flush'in order thatpressure may not. be greatly diminished during the flushing period,otherwise the valve must the adjusted for a specific pressure which ifnot maintained willresult in the valve remaining open indefinitely.

The primary. Object, therefore, of the present invention s 'to constructa valve adapted to rema n open as. long as the volume of water issuflicient to maintain the siphon inth'ecloset bowl and the volume ofwater-delivered to the bowl is by this means determined by the size ofthe pressure tank which is therefore preferably just large enough tomaintain sufficieht-water to proptained by varying the sizeof thepressure .erly flush the bowl. Such an arrangement results 'in a moreeconomical use of water and; a longer or shorter flush may be obtankinstead of by regulating .the flushing valve. However another availablemethod ofvarying the length of a flush is by regulating the velocity ofthe water. supply enterin the tank during the flushin period,there%yregulating the speed at w ich the pressure withinthe tankdiminishes to ac- ,cord with the delivery of water to the bowl.

Another feature ofthe invention resides in the fact that the valve willnot close until the rate of flow appreciably diminishes, there being nolimit to the volume of water that the valve will deliver,- therefore itmay be used if desired to empty a tank containing one hundred or moregallons ofwater as effectively as one containing four or five gallons,commonly employed to flush the usual types of closet bowls.

Another object of the invention is to pro-' vide for a comparativelyslow opening of out of the water-passages within the closet bowl.

vide against the valve closing until the volume and ressure have beenreduced to a "ery small thereby avoiding the hissing noise whichcommonly occursiwhen'a valve is closing under full volume and pressure.Another object of the invention is to control, the final closure of thevalve so as to admit a copious amount of water at a slow rate offiow--the water remaining in the bowl as a seal against sewer gases orother odors.

Another object of the inventionis to provide means insuring theslow-opening and slow closing of the valve which is entirely independentof the means provided to maintain the valve in its open position.

Another feature of the invention is that the means controlling the slowopening and slow closing of the valve is thoroughly cleansed ateach'manipulation of the manually operated means for actuating thevalve. With the foregoing and other objects in .view which will, appearas the description raction of the initial pressure,

Another object of the invention is to proclosed without departing fromthe spirit of the same.

In the drawings accompanying this specification:

Figure 1 is a diagrammatic view partly in perspective and partly insection showing a pressure tank and suitable piping leading from a watersystem-not ind1cated-to a pressure tank that the delivery of waterthereto may compress the air in the tank that the water'contained in itsclosed chamber may be subsequently delivered through a pipe leading to acloset bowlthe delivery of water through said last'named pipe beingcontrolled by a manually operated valve forming the subject matter ofthis invention.

Figure 2 is a vertical cross-sectional view through the flushing valveshowing it in its normal position whereby the water contained in thepressure tank is held against release.

Figure 3 is a similar sectional view through the valve showing thehandle by which it is manually operated in an inclined position toactuate a bell-crank lever, whereby a pin resting upon one of its armsis raised -to force a releasing valve from its seat.

Figure 4: is a similar sectional view with certaln parts broken away andin elevation in which in additon to the releasing valve,

the main valve is also raisedwhile the manually operated lever is shownreleased from manual control and returned 'to its normal, horizontalposition through the action of a springindicated in the precedingfigures-the releasing valve howeveris held off its seat together withthe main valve by the pressure of water flowing from the pressure tankthrough the valve to the closet bowl, as indicated by the arrows.

Figure 5 is a like cross-sectional view showing the releasing valveseated-the main valve being open and the pressure of water entering thechambered'body from the pressure tank now tends to force the main valveto its seat, as shown in Figure 2'the closing movement being relativelyslow. Y

LReferringnow. to. the letters of reference placed upon the drawings inwhich like reference characters designate the same parts in the severalviews:

The valve body A, is connected by suitable piping X, to a pressure tankZ, into which water from a water supply system not shown-flows throughthe piping Y, compressing the a r in the tank in accordance with thepressure of the water "delivered to the latter.

A cap cover A, is bolted to an annular flange a projecting outwardlyfrom the upper end of the valve bodybetween which is secured a diaphramB, preferably formed of leather, which serves also as a washer betweenthe cap-cover and the body of the valve: This diaphram together with allthe working parts connected with the main valve hereinafter moreparticularly described may be removed as a unit from the valve body forinspection ,or repairs.

The main valve D, includes a wingguide E, having a limited verticalmovement in a horizontal partition (Z between the water inlet and thedischarge outlet of the valve body. -Projecting upwardly from thepartition is. an annular rim surrounding the bore forming the seat A ofthe main valve.

Mounted centrally upon a shoulder in an annular screw-threaded extensionof the wingguide is an annular washer F which closes against the seat ofthe main valve said washer being secured by a flanged nut G, screwedupon the annular upwardly exguide.

The washer F is further secured by a collar H having a flangeoverlapping the outer edge of the washer. The collar H is screwed uponthe flanged nut G and also to an annular inverted cup-shaped member Ihaving an annular neck projecting through the diaphram B where thelatter is' engaged by a beveled-edge washer C screwed upon the upwardlyprojecting annular neck I of the cup-shaped element.

C denotes'a flanged nut screwed upon the neck I,, overlapping andbearing against the tapering washer C to hold the diaphragm firmlyagainst a shoulder formed by the wall of the inverted cup I, cham--ferred at the upper outer edge.

guide prevents the pin from dropping out of the latter. The pin Koperates as a contacting means to connect a manually operated bell-cranklever L with a releasing valve M, which is adapted to seat against anannular washer E fitted in the lower end of the upwardly projectingannular extension E, of the wing guide and which is held -in place by anelongated collar E, having a knurled head to facilitate its readyremoval or adjustment.

The releasing valve M is tapered at its lower end and seats against thewall of the washer E, to normally close the opening Y through thelatter.

Extending upwardly from the tapered end of the releasing valve M is atubular portion M having a plurality of holes m adjacent its lowerend-the tubular portion M at its'upper end is provided with aflat disc Mof relatively large diameter which is adapted to seat at its outermarginal edge against a shoulder 1 formed-in the bowl of the invertedcup-shaped element-there being a space I above the disc to allow egressof water'through the releasing valvewhen in its open or raised positionwith the disc.

of the valve against the'shoulderI of the inverted cup-shaped element.

Sleeved within the tubular portion of the releasing valve is a coiledspring N bearing at its lower end against the wall of the ta- ,peringvalve and at its upper end against the overlapping flange of the nut C,screwed upon the tubu ar neck of the inverted cupshaped' element.

Between the cap J and the counterbored annular neck of the nut C isplaced a disc P, through which is drilled a relatively small holethesize of which determines the speed at which the valve may open andclose-water being expelled through the hole during the openingphase andis again admitted during the closing phase of movement of the mainvalve.

While the main valve is closing water passes through the aperture in thedisc comparatively slowly, while on the contrary when the valve isopening the water pressure against the lower surface of thediaphraginforces the water through the aperture in the disc vwith comparativerapidity'thus any foreign matter that may have become lodged around thedisc is washeddown and out.

The aperture. in the disc is further cleansed at each flush by means ofa wire stem Qpreferably of gold 'which passes through the disc apertureand projects from ,the upper end of. a rod Q, slidable within a tube R,sleeved within the coiled spring N, the upper end of the tube beingflanged to overlap the counterboredwall of; the annular; stem of the nutCthe lower end-of the tube'being flanged inwardly to engage a flattenedportion Q? of the rod-to prevent.

the latter dropping through the tube when removing the parts forinspection or repairs. The rod Q isloosely fitted in'the lower end ofthe tube and projects through the latter and rests upon the releasingvalve that it may be raised when the valve is lifted by the manualoperation of the bell-crank lever.

It will now be apparent that each time the releasing valve is manuallyoperated the wire Q is moved upwardly through the aperature in the'regulating disc, thereby removing any foreign particles which may havefound temporary lodgment at this point.

The disc is preferably made of non-cor rodible metal or other material,reducingto the minimum thepossibility of the aperture becomingcloggedthe pinproviding a facile means for cleaning the aperture in thedisc without taking the valve apart.

Attention is again directed to the beveled edge washer C screwed uponthe neck I of the mverted cupshaped, element, so; constructed that whenpressure is exerted against the lower face of the diaphragm B, thediaphragm is forced against its bev-' eled portion, thereby transferringthe presis operated.

The end of the handle W projects through acontracted opening in the endof the collar S, screwed intoa lateral extension of the valve body andis fitted with an areshaped end W? adapted to bear against a springactuated plunger T, supported centrally within the collar by a plug T,havinga. flange projecting between the end of the collar S and ashoulder in the wall of the valve body. i

V denotes a rubber gasket or washer over lapping the end of the plug T,'its marginal edge extending between the plug andvalve body and issecured to the plunger by a milled screw V which in turn bears againstone of the arms of the bell-crank lever, whereby the lattermay beactuated upon operating the handle.

Having indicated the erence letters the construction and operation ofthe device will be readily understood:

,The valve having been connected with the pressure tank Z -which maybeeither at the same altitude as the valve or higher or lower as desired,the pressuretank' being in turn connected with the source of watersupplywater is admitted to the tank fromsaid source of supply.-

The lncom'ing' water compresses the air within the tank until'itequalsthe pressure v crank lever L, whereby the releasing valve severalparts by refunckar which the water is delivered to the tan The valveduring this period is normally closed except that it may beoperatedseveral times to expel air from the connecting pipes and chamberin the valvebody above the diaphragm. The operation thereafter is asfollows:

Manipulation of the manually operated handle ll' actuates the bell-cranklever L which in turn pushes the loose fitting pin K upwardly in thebore of the wing-guide E until it impinges upon the lower end of thereleasing valve M. forcing the latter from its seat, the disc M beingforced upwardly bythevalve against the shoulder 1 of the cup-shapedelement Ia unitary part of the main valve.

Attention is now called to the relatively small opening 2' between thecollar H and the. inverted cup-shaped element I, of the mainvalve-through which and the ports 2, the full pressure of water may passto the lower face of the releasing valve D. It also circulates throughthe space it, between the outer diameterof the collar Hand the valvebody, so that the water pressure may pass to the lower face of thediaphragm. This water pressure holds the release valve in its .raisedpositionwhereupon the water above the diaphragm of the main valve passesdown and outwardly through the aperture in the regulating .discthereuponthe main valve slowly opens.

The full flush however cannot be attained until the collar at the top ofthe wing guide has been raised above the opening through the main valveseat. During this interval a relatively small amount of water passesthrough the grooves e of the collar of the wing-guide which serves thepurpose of gradually expelling the air that is normally in the waterpassage of the closet bowl, thereby eliminating the gurgling or gushingnoises that ensue when ample water to create a full flush is admittedinstantaneously to the bowl. I

As the valve continues to rise the volume of water passing through thevalve increases until suflicient to create and maintain siphonage of thebowl-the valve remaining in full open position as long as the volume isample to maintain siphonage. The length of time during which the bowlwill continue to siphon is dependent upon the size of the pressure tankemployed, plus the volume of supply that is added to that in thepressure or storage tank while the valve is open.

.When the pressure tank is empty, or nearly so, the volume necessarilyis greatly decreased and the pressure of water entering a the main valvebecomes insufficient to maintain the releasing valve in its openposition. The releasing valve, therefore, is forced to its. seat by thecoiled spring within the main valve. The force of gravity plus the smallremaining water pressure combine at this point to seat the main valveand the water flowing through the small opening provided between thecollar and the inverted cupshaped element of the main valve passesupward and through the aperture in the disc of the releasing valve.

This closing movement however is comparatively slow and until the mainvalve is entirely closed water flows past the collar to the top of thewing guide. The volume of water that passes however is much too small tomaintain a siphon and therefore it remains in the bowl forming a copiousseal against sewer gases.

Owing to the fact that the water pressure is now small, the finalclosure of the main valve is practically noiseless in contrast to thewhistling or hissing noises inevitable with valves of this type whichclose under, or nearly, full primary pressure.

Valves of this type designed to close under full water pressure usuallyWaste considerable water before finally closing as the pressure isconsiderably diminished after the valve is fully open rendering theminapplicable for use with a pressure tank unless the tank is largeenough so that a single flush only slightly diminishes the pressure inthe tank.

. The present valve is constructed primarily for use with acomparatively small pressure tank which together with a certain quantity of supply water entering the tank while emptying provides the exactquantity of water required for each flush, and due to its slow openingand closing while the water pressure is practically nil a quietness ofoperation is attained which is not secured by otherwalves of this type.
